Hello, No, that's not possible. OpenTURNS' functions return vectors anyway.
If you absolutely have to reuse func as is you could still create a decorator that wraps your function and packs it in a list. j > De: "roy" <[email protected]> > À: "users" <[email protected]> > Envoyé: Mercredi 1 Février 2017 14:07:35 > Objet: [ot-users] PythonFunction from a scalar output function > Hi, > Is it possible to create a PythonFunction without the function returning a > list? > This does not work: > def func(x): > f = 0. > for i in range(2): > f += np.sin(x[i]) * np.sin((i + 1) * x[i]** 2 / np.pi) ** (2 * 10) > return -f > f = ot.PythonFunction(2, 1, func) > This works: > def func(x): > f = 0. > for i in range(2): > f += np.sin(x[i]) * np.sin((i + 1) * x[i]** 2 / np.pi) ** (2 * 10) > return [-f] > f = ot.PythonFunction(2, 1, nunc) > Thanks, > Pamphile ROY > _______________________________________________ > OpenTURNS users mailing list > [email protected] > http://openturns.org/mailman/listinfo/users -- Julien Schueller Phimeca Engineering www.phimeca.com
